Class Assertions

struct CowlClsAssertAxiom : public CowlAxiom

Represents a ClassAssertion axiom in the OWL 2 specification.

Public Static Functions

static inline CowlClsAssertAxiom *cowl_cls_assert_axiom(CowlAnyClsExp *exp, CowlAnyIndividual *ind, CowlVector *annot)

Returns a retained class assertion axiom.

Parameters
  • exp – The asserted class expression.

  • ind – The assertion individual.

  • annot – [optional] The annotations.

Returns

Retained axiom, or NULL on error.

static inline CowlClsAssertAxiom *cowl_cls_assert_axiom_retain(CowlClsAssertAxiom *axiom)

Retains the specified axiom.

Parameters

axiom – The axiom.

Returns

Retained axiom.

static inline void cowl_cls_assert_axiom_release(CowlClsAssertAxiom *axiom)

Releases the specified axiom.

Parameters

axiom – The axiom.

static inline CowlClsExp *cowl_cls_assert_axiom_get_cls_exp(CowlClsAssertAxiom *axiom)

Gets the class expression that is asserted to be a type for an individual by this axiom.

Parameters

axiom – The axiom.

Returns

The class expression.

static inline CowlIndividual *cowl_cls_assert_axiom_get_ind(CowlClsAssertAxiom *axiom)

Gets the individual that is asserted to be an instance of a class expression by this axiom.

Parameters

axiom – The axiom.

Returns

The individual.

static inline CowlVector *cowl_cls_assert_axiom_get_annot(CowlClsAssertAxiom *axiom)

Gets the annotations of the specified axiom.

Parameters

axiom – The axiom.

Returns

The annotations.

static inline CowlString *cowl_cls_assert_axiom_to_string(CowlClsAssertAxiom *axiom)

Returns the string representation of the specified axiom.

Note

The returned string is retained, so you are responsible for releasing it.

Parameters

axiom – The axiom.

Returns

String representation, or NULL on error.

static inline bool cowl_cls_assert_axiom_equals(CowlClsAssertAxiom *lhs, CowlClsAssertAxiom *rhs)

Equality function.

Parameters
  • lhs – LHS of the equality relation.

  • rhs – RHS of the equality relation.

Returns

True if the equality relation holds, false otherwise.

static inline ulib_uint cowl_cls_assert_axiom_hash(CowlClsAssertAxiom *axiom)

Hash function.

Parameters

axiom – The axiom.

Returns

The hash value.

static inline bool cowl_cls_assert_axiom_iterate_primitives(CowlClsAssertAxiom *axiom, CowlPrimitiveFlags flags, CowlIterator *iter)

Iterates over the primitives referenced by the specified axiom.

Parameters
  • axiom – The axiom.

  • flags – Iteration flags.

  • iter – The iterator.

Returns

True if the iteration was completed, false if it was stopped.
